That is correct. There will be nominal fees associated with upgrading your club in various ways. Specific details will probably not be released until the next phase of CC's is ready to go, which as of this moment is still TBA.
I'm sorry that we cannot go into more specific details in advance, but some information could be considered sensitive to some parties if it's released too early. Anything that is tentatively decided now may be tweaked many times before the final version is released, sometimes just a few days prior to the release going live. Since things do change at the last minute we do not wish to put ourselves in a position where we set false expectations and are then forced to disappoint members by telling them specific features we "promised" suddenly can't be released.
